I’m looking for a region that speaks both Portuguese and Spanish but also maybe another similar, less spoken Romance language.
It can have similar culture but also different, unique culture. Either has to be in Spain or Portugal or nearby them so I could just drive to either country.
If you wannt to try something unique go to miranda do douro in portugal, where they speak mirandese, with only 3500 native speakers
One of Portugal’s official languages! And AFAIK even older than modern portuguese
isto. this. ^
